Scientists have found that the shape of sand grains influences the liquefaction of sand which is one of the major factors behind the collapse of structures during earthquakes.<\/span><\/p>\n

What is the Liquefaction of sand?<\/b><\/h5>\n

Liquefaction of sand is a <\/span>phenomenon in which the strength and stiffness of a soil are reduced by earthquake shaking or other rapid loading and lead to the collapse of s<\/span>tructures resting on the liquefied ground.<\/span><\/p>\n

What have the scientists found in this study?<\/b><\/h5>\n

Scientists have found that the shape of sand grains influences the liquefaction of sand. For instance, <\/span>natural sand with a regular shape liquefies easily compared to sand with an irregular shape.<\/span><\/p>\n

This is because the shear force <\/span>(unaligned forces<\/span> pushing one part of a body<\/span> in one specific direction and another part of the body in the opposite direction) <\/span>required to break the inter-particle locking is more for the grains with relatively irregular shapes.\u00a0<\/span><\/p>\n

Hence, the scientists concluded that <\/span>natural sand used in structures like slopes and retaining walls can be replaced with irregular manufactured sand to improve stability and sustainability.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
